Data Mining - Concepts and Techniques.

The objective of this paper is to give a comprehensive introduction to applied cryptography with an engineer or computer scientist in mind. The emphasis is on the knowledge needed to create practical systems which supports integrity, confidentiality, or authenticity. Topics covered includes an introduction to the concepts in cryptography, attacks against cryptographic systems, key use and handling, random bit generation, encryption modes, and message authentication codes. Recommendations on algorithms and further reading is given in the end of the paper. This paper should make the reader able to build, understand and evaluate system descriptions and designs based on the cryptographic components described in the paper.

Trust and reputation are central to effective interactions in open multi-agent systems (MAS) in which agents, that are owned by a variety of stakeholders, continuously enter and leave the system. This openness means existing trust and reputation models cannot readily be used since their performance suffers when there are various (unforseen) changes in the environment. To this end, this paper presents FIRE, a trust and reputation model that integrates a number of information sources to produce a comprehensive assessment of an agent's likely performance in open systems. Specifically, FIRE incorporates interaction trust, role-based trust, witness reputation, and certified reputation to provide trust metrics in most circumstances. FIRE is empirically evaluated and is shown to help agents gain better utility (by effectively selecting appropriate interaction partners) than our benchmarks in a variety of agent populations. It is also shown that FIRE is able to effectively respond to changes that occur in an agent's environment.

Providing security and privacy in mobile ad hoc networks has been a major issue over the last few years. Most research work has so far focused on providing security for routing and data content, but nothing has been done in regard to providing privacy and anonymity over these networks. We propose a novel distributed routing protocol which guarantees security, anonymity and high reliability of the established route in a hostile environment, such as an ad hoc wireless network, by encrypting the routing packet header and abstaining from using unreliable intermediate nodes. The major objective of our protocol is to allow trustworthy intermediate nodes to participate in the path construction protocol without jeopardizing the anonymity of the communicating nodes. We describe our protocol, SDAR (secure distributed anonymous routing), and provide its proof of correctness.

SDAR: a secure distributed anonymous routing protocol for wireless and mobile ad hoc networks

Security, anonymity, and scalability are still important issues for mobile ad hoc network routing protocols. We first expose the limitations of several existing mobile ad hoc network routing protocols with security and anonymity constraints and analyze their scalabilities. Based on the analysis, we propose a new anonymous dynamic source routing protocol (AnonDSR) to provide three levels of security protection. We compare their scalabilities with security constraints, and analyze the new protocol to show it has strong security and anonymity protection, and very good scalability.

AnonDSR: efficient anonymous dynamic source routing for mobile ad-hoc networks

For a variety of advantages, universities and other organizations are resorting to e-learning to provide instruction on-line. While many advances have been made in the mechanics of providing online instruction, the needs for privacy and security have to-date been largely ignored. This paper examines privacy and security issues associated with e-learning. It presents the basic principles behind privacy practices and legislation. It investigates the more popular e-learning standards to determine their provisions and limitations for privacy and security. Privacy requirements for e-learning systems are explored with respect to the “Privacy Principles”. The capabilities of a number of existing privacy enhancing technologies, including methods for network privacy, policy-based privacy/security management, and trust systems, are reviewed and assessed.

Privacy and Security in E-Learning

Discussions at the 5th Workshop on Deception, Fraud and Trust in Agent Societies held at the 1st International Joint Conference on Autonomous Agents and Multi-Agent Systems (AAMAS 2002) centered around many important research issues. This paper attempts to challenge researchers in the community toward future work concerning three issues inspired by the workshop’s roundtable discussion: (1) distinguishing elements of an agent’s behavior that influence its trustworthiness, (2) building reputation-based trust models without relying on interaction, and (3) benchmarking trust modeling algorithms. Arguments justifying the validity of each problem are presented, and benefits from their solutions are enumerated.
